What will the `gettype()` function return for an array in PHP?

The gettype() function in PHP is designed to return the type of the variable passed to it as a string. When you pass an array to the gettype() function, it accurately identifies and returns the type as "array". This is an important feature that allows developers to understand the nature of the variable they are working with, especially in situations where the datatype may affect logic and application behavior.

Understanding the output of gettype() is essential for managing data types effectively in PHP. Arrays are particularly significant in this context, as they are commonly used for storing collections of data. Knowing that gettype() returns "array" helps developers confirm the structure of their data before performing operations like loops and iterations, which are fundamental in working with arrays.
